1 INTERPRETATION IN INTERNATIONAL LAW Interpretation in international law? Are there any principles concerning the interpretation of international law? What is the legal character of these principles? Do they relate to particular source of international law? Are of general application to any international norm? 1

2 Points of reference for the process of treaty interpretation: whether a document is a treaty (in the sense of the VCLT, or public international law) scope of a treaty normative substance of a treaty direct applicability of a treaty Temporal element of interpretation Static approach (principle of contemporaneity) the meaning of treaty provisions and the circumstances prevailing at the time of the conclusion of the treaty Dynamic approach (principle of evolutionary interpretation) the meaning of a treaty at the time of its interpretation generic terms, whose content the parties expected would change through time (intended to analyse its meaning in light of the circumstances prevailing at the time of interpretation) 2

3 CUSTOMARY CHARACTER OF THE RULES ON TREATY INTERPRETATION (ART. 31 AND 32 VCLT) Widely shared by other international courts ITLOS, ECtHR, CJEU and the dispute settlement bodies of WTO, as well as by many arbitral institutions treaty practice (e.g. Free Trade Agreement concluded between European Union and its Member States, of the one part, and the Republic of Korea, of the other part) Consequences of customary character? International judicial practice methodology followed during treaty interpretation (with reagrd to temporal element) the static approach as a basic rule and as a particular application of the doctrine of inter-temporal law ICJ, Dispute Regarding Navigational and Related Rights the terms used in a treaty must be interpreted in light of what is determined to have been the parties common intention, which is, by definition, contemporaneous with the treaty s conclusion 3

4 the meaning of a treaty for purposes of good-faith compliance with it, to ascertain the meaning a term had when the treaty was drafted, since doing so can shed light on the parties common intention ICJ, Namibia case Interpretation: "the strenuous conditions of the modern world", "the well-being and development" of the peoples concerned, the concept of the "sacred trust viewing the institutions of 1919, the Court must take into consideration the changes which have occurred in the supervening half-century, and its interpretation cannot remain unaffected by the subsequent development of law, through the Charter of the United Nations and by way of customary law an international instrument has to be interpreted and applied within the framework of the entire legal system prevailing at the time of the interpretation two-tier process: whether a term is meant by the parties to be interpreted in a dynamic manner (intention) whether a concept is embodied in the treaty that is, from the outset, evolutionary meaning at the time of interpretation development of linguistic usage international law other relevant circumstances up to that moment 4

5 Please provide arguments in favour / against static as well as dynamic interpretation Examples from Telders case 2017? Examples form international practice? Cases? Real world? Which doctrine is closer to the characteristics of public international law? Specific rules of interpretation for certain treaties General rules of interpretation undergo some modifications when applied to certain types of treaties? Human rights treaties justification: beneficiaries, or even the true addressees, of the treaty provisions are individual Interpretation process requires different rules? Constituent instruments of international organizations Specific interpretation problems owing to their character which is conventional and at the same time institutional (ICJ, Nuclear Weapons) What should be taken into consideration while interpreting constituent instruments of international organazation? 5

6 elements which may deserve special attention when the time comes to interpret constituent treaties the very nature of the organization created, the objectives which have been assigned to it by its founders, the imperatives associated with the effective performance of its functions, as well as its own practice. [ICJ, Nuclear Weapons] Interpretation rules outside VCLT? Principle in dubio mitius treaties are to be interpreted in favour of State sovereignty developed by PCIJ (Wimbledon case, Free Zones case) subsidiary character - it will be only when, in spite of all pertinent considerations, the intention of the Parties still remains doubtful, that that interpretation should be adopted which is most favourable to the freedom of States. (PCIJ, River Oder) Limitation contrary to the plain terms of the article and would destroy what has been clearly granted Doubtful customary character 6

7 Principle of effectiveness treaty provisions are to be interpreted so as to give them their fullest weight and effect and in such a way that a reason and a meaning can be attributed to every part of the text ICJ, CERD case the words ought to be given appropriate effect to the phrase which is not settled in Art 22 of the Convention and discarded a reading of that phrase which would render it meaningless and devoid of any effect particular application of the object and purpose test and the good faith rule Principle of restrictive interpretation of exceptions a particular application of the object and purpose rule, relating to the telos of the general rule Contra proferentem rule the rule according to which a text that is ambiguous must be construed against the party who drafted it ICJ, Fisheries case rule may have a role to play in the interpretation of contractual provisions [but ICJ denied its application to declarations of acceptance of the Court and reservations made thereto] Is it actually possible to use the contra proferentem rule to interpretation of treaties? 7

8 On the basis of VCLT what is the general rule of treaty interpretation? Is there any hierarchical or chronological order of treaty interpretation? The general rule of treaty interpretation based on the textual approach text is presumed to be the authentic expression of the intentions of the parties three separate principles, combined in one single rule of interpretation interpretation in good faith [pacta sunt servanda] recourse to the ordinary, as opposed to a special, meaning of the terms used in the treaty the ordinary meaning is not to be determined in the abstract but in the context of the treaty and in the light of its object and purpose 8

9 Ordinary meaning of the terms: linguistic and grammatical analysis of the text of the treaty the grammatical form of a treaty term encompasses the tense in which a specific provision has been phrased WTO Appellate Body In general, requirements expressed in the present perfect tense impose obligations that came into being in the past, but may continue to apply at present. In determining ordinary meaning of terms, two aspects are to be taken into consideration: temporal aspect of the ordinary meaning each authentic treaty language Context: General rule of interpretation does not allow establishing an abstract ordinary meaning of a phrase divorced from the place which that phrase occupies in the text to be interpreted Systematic structure of a treaty is thus of equal importance to the ordinary linguistic meaning of the words use 9

10 Elements of context: the title of a treaty ICJ, Oil Platform case: Oil Platforms case: For the meaning of the word commerce in a bilateral treaty concluded by Iran and the US, the Court turned, inter alia, to the actual title of treaty which referred rather broadly to economic relations and thereby suggested a wider reading of the term. punctuation and syntax ICJ, Aegean Sea Continental Shelf case, the French phrase et, notamment, and explicitly pointed to the commas used ["et, notamment, les différends ayant trait au statut territorial de la Grèce" ] structure of the sentence ICJ, Land, Island and Maritime Frontier Dispute (El Salvador v Honduras) while interpreting the phrase to determine the legal situation No doubt the word determine in English (and, as the Chamber is informed, the verb determinar in Spanish) can be used to convey the idea of setting limits, so that, if applied directly to the maritime spaces its ordinary meaning might be taken to include delimitation of those spaces. But the word must be read in its context; the object of the verb determine is not the maritime spaces themselves but the legal situation of these spaces. 10

11 the use of the same term elsewhere in the treaty or different phrases of the same treaty dealing with the same issue in different wordings ICJ, Land, Island and Maritime Frontier Dispute (El Salvador v Honduras) to delimit the boundary line [...] ( Que delimite la linea fronteriza [...] ) regarding the land frontier, while confining the task of the Chamber as it relates to the islands and maritime spaces to determine [their] legal situation [...] Comparison of the term in question with the analogous wording of a related treaty ICJ, Land, Island and Maritime Frontier Dispute (El Salvador v Honduras) Article 18 of the General Treaty of Peace, which, in paragraph 2, asks the Joint Frontier Commission to delimit the frontier line in the areas not described in Article 16 of this Treaty, while providing in paragraph 4, that it shall determine the legal situation of the islands and maritime spaces. the role of extrinsic material in the process of interpretation (art. 31 (2) and (3) VCLT) 11

12 Object and purpose (teleological interpretation) Principle of effectiveness the terms of a treaty are to be interpreted in a way that advances the latter s aims any interpretation that would render parts of the treaty superfluous or diminish their practical effects is to be avoided both elements are usually amalgamated into one single test applying the telos of the treaty How to determine object and purpose? general clauses specifically stating treaty s purposes title of the treaty preamble of a treaty type of treaty reading of the whole treaty contrasting the treaty in question with relevant treaties of the same kind 12

13 The consideration of object and purpose finds its limits in the ordinary meaning of the text of the treaty Iran-US Claims Tribunal once pointed out: Even when one is dealing with the object and purpose of a treaty, which is the most important part of the treaty s context, the object and purpose does not constitute an element independent of that context. The object and purpose is not to be considered in isolation from the terms of the treaty; it is intrinsic to its text. It follows that, under Article 31 of the Vienna Convention, a treaty s object and purpose is to be used only to clarify the text, not to provide independent sources of meaning that contradict the clear text. Good faith principle the most fundamental rule of the law of treaties, every treaty must be performed in good faith requirement of reasonableness qualifying the dogmatism that can result from purely verbal or, for that purpose, excessively teleological analysis obligation of result (to avoid manifestly absurd or unreasonable) Example: the reference in Art 23 (1) of the UN Charter to the Republic of China and the Union of Soviet Socialist Republics must today reasonably be taken to refer to the People s Republic of China and to the Russian Federation, respectively 13

14 Elements of context (art. 31 (2) VCLT) Assumption: a unilateral document cannot as such be regarded as part of the context but has, in order to attain that status, to receive some kind of acceptance by the other parties authentic interpretation Legal status of documents extrinsic to a treaty: a document is part of the actual treaty consensus [object, not an instrument of interpretation] documents outside the treaty consensus, but related to its development [interpretative instruments] mere travaux preparatoires [supplementary means art. 32 VCLT] conditions for related material to become extrinsic context of a treaty: object of general consensus of all parties consensus must be born by all parties Material must relate to the substance of the treaty Specyfing or claryfing certain concepts used therein, limiting its field of aplication (relation must be of substance] in connexion with the conclusion of the treaty Nexus in purpose and substance Cretain temporal proximity to the conclusion 14
